Grob's Attack is an unconventional chess opening where White immediately moves the king knight's pawn two squares ahead:
The opening takes its name from Swiss International Master Henri Grob (1904–1974) who analyzed it extensively and played hundreds of correspondence games with it. In Grob's newspaper column analysis of this opening, he referred to it as the Spike Opening, a name which still enjoys limited usage. Other early references used the name Ahlhausen's Opening, after Carl Ahlhausen (1835–1892) of Berlin, one of the first to play 1.g4. Savielly Tartakower sometimes played this opening in simultaneous exhibitions and called it the Genoa or San Pier D'Arena Opening, after the city and suburb of Genoa where he first used it. In the Czech Republic and Slovakia 1.g4 is called Fric's Opening, and in other parts of the world it is called Kolibri's Opening.
It is considered an irregular opening, so it is classified under the A00 code in the Encyclopaedia of Chess Openings.
The Grob is generally considered inferior and is usually not employed in serious competition. International Master John Watson writes, "As far as I can tell, 1 g4 is competitive with 1 h4 for the honour of being White's worst first move. Against an informed or skilled opponent, it is simply masochistic."
Nonetheless, International Master Michael Basman and Grandmaster Spyridon Skembris are advocates of the opening. It has a certain surprise value, and the average player is unlikely to know how to refute it and more likely to get overconfident and make mistakes. Moreover, the lack of theory along this line may negate the repertoire of an experienced opponent. Intuitive play by White can lead Black into dangerous traps. Many of these traps rely on Black's replying with 1...d5, attacking the pawn with his queen's bishop. After 2.Bg2 Bxg4!?, White has an attack after 3.c4 and eventually Qb3, aiming at the weakened squares d5 and b7, an attack that may well be worth a pawn.
